What is not and is UCLP?

What is not UCLP?
Confusion about UCLP
> UCLP is often wrongly associated with other
dynamic optical switching protocols.
> UCLP has nothing to do with optical control
planes or providing bandwidth on demand.
> Primary purpose is NOT
–
–
–
–
a dynamic switched optical networks
a reservation and leasing of wavelength resources
an end-to-end optical VPNs
an inter-domain connection of LightPaths
What is UCLP?
UCLP Objectives
> UCLP is an IP network provisioning and configuration tool
– it allows the creation of application or discipline specific IP
networks that can be built from optical paths obtained from a
mix of heterogeneous network resources across different
management domains
– Similar in concept to X-bone VPN overlay network, except at
layer 1
> User controlled traffic engineering
– Active replacement for Sockeye and Route Science
– Alternative to MPLS
What is UCLP?
CA*net 4; a layer 1 network
1st & 2nd wavelengths – 10 Gbps
3rd wavelength – 10 Gbps
4rd and 5th wavelengths are coming soon…
What is UCLPv1?
What is a LightPath?
> According to “User controlled Lightpath Definition Document
(http://www.canarie.ca/canet4/library/c4design/user_controlled_def
inition.ppt)”, created by Bill St. Arnaud in December 2002:
– Any uni- or bi-directional point to point connection with effective
guaranteed bandwidth
> Examples of LightPaths on CA*net: STS channels on a SONET or
VC4 channels on SDH circuits
LightPath has
Bandwidth, start and
end points
ons-ott01; slot 12;
port 1; channel 72
STS24c (OC24)
ons-tor01; slot 5; port 1; channel 72
What is UCLPv1?
CA*net 4 is a pool of LightPaths
- Which have been create by UCLP admin (e.g. c4noc).
What is UCLPv1?
What are the Users?
You!
?
That simply wants
to best achieve
your job!
What is UCLPv1? Users take
control of LightPaths on CA*net4
- Ownership of LightPaths is achieved via the lease process.
- Lease period has a start and end dates
.
What is UCLPv1? Users creates
an e2e connections on CA*net4
- Users access the LightPaths and run their applications during the
requested period.
access LPs
concatenate LPs
access LPs
What is UCLPv1? It talks about
users empower the network!
> During the period where a user owns
the LightPaths, it could
– Partition LightPaths;
– Concatenate LightPaths;
– Advertise unused LightPaths (i.e. make them
available for another users).
– Create/delete the e2e connections (access
LightPaths).
What is UCLPv1? Users deletes
the e2e connections on CA*net4
At the end of the lease period, the users loose the ownership of
the LightPaths.
LightPaths come back the pool .
What is UCLPv2?
From LightPaths to APNs…
> Now let’s imagine that the users would like to manage a subset
of CA*net as part of their network including add/drop, routing, partition,
concatenate, etc.

What is UCLPv2?
From LightPaths to APNs…
> UVLPv2 is an extension of UCLPv1’s concepts of LightPaths and Users.
> In UCLPv2, the LightPaths and Network Interface (e.g. the GigE ports)
become some web services (WS) resources.
> The APN resource list is a pointer to a set of the above-defined WS,
> Finally, an APN (Articulated Private Network) is essentially a workflow
script created by the Network Administrator (e.g. CANARIE) that points to
a collection of Network LightPaths and Interfaces (e.g. the APN resource
list), destined to the APN administrators (e.g. NRC).
> The APN Administrators can download and run the APN workflow script
and create functioning APN (e.g. NRC’s CA*net 4 APN).
> An APN could be merge to other APNs for forming a new APN (e.g. NRC’s
CA*net 4 APN + NRC’s private APN + SURFnet’s APN).
> The APN could be re-advertise all or some of the APN resource list to other
users.
> Finally, the normal users (e.g. NRC’s users) can take control of the APNs
resources and establish their own e2e connections.
What is UCLPv2?
UCLPv2 in a nutshell!
> UCLPv2
– Graphical interface to allow users to create
Articulated Private Networks (APNs)
– All lightpaths represented as web services
that are consumed by user by linking through
portal on workflow engine
> BPEL or Keppler to link APNs together to
form end to end LightPaths and to link
instruments.
